The answer to 'why is my shingles damaged' is that there are several common causes, including severe weather, age and wear, improper installation, and lack of maintenance. Damaged shingles may appear cracked, curled, missing, or discolored. This can lead to leaks, water damage, and energy efficiency issues.
If the damage is limited, you may be able to make minor repairs yourself, like replacing a few shingles. However, widespread or severe damage likely requires a professional roofer to inspect the roof, identify the root cause, and perform a full repair or replacement. They can ensure the work is done properly to protect your home long-term.
